1 NAME
2 RCU - Remote Control Unit Interface
3
4 SYNOPSIS
5 use RCU;
6
7 DESCRIPTION
8 This module provides a generic interface to remote control units (only
9 receivers at the moment, as I cannot test more). It only provides an
10 abstract management interface, other modules are required for the
11 hardware access (RCU::Irman and RCU::Lirc are included, however).
12
13 GETTING STARTED
14 Please read RCU::Receipts to get some idea on how to proceed after you
15 installed the module (testing & standard techniques).
16
17 THE RCU CLASS
18 The RCU class provides a general interface to anything you might want to
19 do to, it represents your application.
20
21 $rcu = new RCU "interface-spec"
22 Creates a new RCU application. "interface" must be an interface
23 specification similar to DBI's DSN:
24
25 RCU:ifname:arg:arg...
26
27 Examples: low-level interface (without "RCU::" prefix) or an
28 arrayref containing name and constructor arguments. If the interface
29 name has a "::" prefix it will be used as-is (without that prefix,
30 of course).
31
32 For a much better interface, see RCU::Event.
33
34 $rcu->interface
35 Return the RCU::Interface object used by this RCU object.
36
37 ($keycode, $repeat) = $rcu->get
38 ($keycode, $repeat) = $rcu->poll
39 Simplified interface to the RCU (See also RCU::Event), return a
40 cooked keycode and a repeat count (initial keypress = 0, increasing
41 while the key is pressed). If "get" is called in scalar context it
42 only returns unrepeated keycodes.
43
44 This interface is problematic: no key-up events are generated, and
45 the repeat events occur pseudo-randomly and have no time relation
46 between each other, so better use the event-based interface provided
47 by RCU::Event.
48
49 THE RCU::Key CLASS
50 This class collects information about rcu keys.
51
52 THE RCU::Interface CLASS
53 "RCU::Interface" provides the base class for all rcu interfaces, it is
54 rarely used directly.
55
56 fd Return a unix filehandle that can be polled, or -1 if this is not
57 possible.
58
59 ($time, $raw, $cooked) = $if->get
60 ($time, $raw, $cooked) = $if->poll
61 Wait until a RCU event happens and return it. If the device can
62 translate raw keys events (e.g. hex key codes) into meaningful names
63 ("cooked" keys) it will return the cooked name as second value,
64 otherwise both return values are identical.
65
66 "get" always returns an event, waiting if neccessary, while "poll"
67 only checks for an event: If one is pending it is returned,
68 otherwise "poll" returns nothing.
